' ing the blades thereon as made of curved FAtm-tu. a citizen of the United States, and a resident of Chicago. lll the county of Cook and State of Illinois; have invented certain new and useful Improvements in llydro plane-Boats; andI do hereby declare that the following is a full. clear, and exactv description thereof, reference being had to the aceompan ving drawings. and to the letters of I bow and rearwardly to a rounded stern.

reference marked thereon, which form a part of this specification.

This invention relates to imprm'ements in E that class of water craft known as hydroplane boats, which are. equipped with melmed surfaces or planes designed to act on the water when the boat is traveling at high speed In a manner to lift the boat and lessen the submerged area or the hull, with eonsequcntreduction of resistance and the attainment of high speed in proportion to the propellin power employed.

The object of my invention is to produce a craft for pleasure or commercial use, in t which 15 combined the desirable features and which has the advantages of both a hydroplane boat and an ordinary boat supported by displacement of the Water.

The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

My invention may be better understood by reference to the accompanying drawings, in which,

Figure 1 is a top plan view of a hydroplane boat embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a bottom plan view thereof. Fig. 4 is a side elevation of the rear part of said hydroplane boat, showing parts adjacent to the paddle wheel in section, taken on the line 44 of Fig. 1. Fig. 5 is a vertical section taken on the line 55 of Fig. 4. perspective of one of the hydroplane members constituting a part of said invention. Fig. 7 is a side elevation thereof. Fig. 8 is Fig. 6 is a view in-! a verti al section taken on the line S-S of Y separated sections located at opposite side Fig. 7. Fig. 9 is a transverse section of the boat, taken on line 9-9 of Fig. 2,1d1owing 1 member 1. 18 provided in HS forward part he paddle wheel in elevation. Fig. 10 is a sectional view. like Fig. 9. illustrating a form.

.\s shown in said drmvings. indicates the hull of a boat which is generally similar in shape to the hull of speed boats as at present constructed and which has a flat or nearly at bottom surface. Said hull has a long pointed bow with its grentert beam at a point about midway of its length and from such point tapering forward to the B indicates a transversely arranged paddle wheel for propelling the boat. which is located about midway of the. length of the boat and at the widest part. of the lmll. Said paddle wheel is located in a tramsveise cylindric casin; or housing A. the lower margins of llCll are joined to the margins of a rectangular opening in the bo tom of the hull, and the paddle wheel extends at its lower part downward tl.rough the open bottom of the housin".

C indicates an engine or motor for driving said addle wheel. which. as shown in the drawings. is located forward of soul paddle wheel and consists of a garolene engine having four upright power cylinders.

acting on a crank shaft C. which extends transversely of the hull and parallel with the axis of rotation of the paddle wheel.

D. E. F. i and H indicate hvdroplanc members which are arranged on the bottom of the boat in such manner that by their reaction on the water in the. forward movement of the boat they tend to lift the hull out of the water. Said h \-'droplane members are inclined downwardly from their front toward their rear ends and extend across the bottom of the lmll. The members I). E and F are located forward of the paddle wheel B and the members G and ll at the rear of said paddle wheel.

I indicates a vertical rudder at the rear end of the boat and J a center-board at the forward part thereof.

The forward hydroplane member D is shown as consisting of two longitudinally of the center-b ard J. and the lrvdroplane ally displaced when it encounters swells or waves at an angle. As illustrated in the drawings, said center-board is mounted on a pivot j at its forward end so that its rear end can be lifted when passing over a bar or running the boat u on a beach."The rudder I may be of or inary construction, butas illustrated is also pivoted to permit it swinging upwardly for the same purpose as in the case of the center-board; said rudder being shown as pivoted at its forward end by a pivot-i to a rudder post I.

Now referring more particularlyto the paddle wheel B and other features of the propelling means, the same embrace features of construction as follows: The paddle wheel B com rises a closed hollow cylindrical drum 1 fixed to a transversely arranged horizontal shaft B and having on its exterior cylindrie surface radially extending paddle blades 6 b. Said paddle blades 6 are arranged upon the exterior surface of the drum B in s iral or oblique direction and are arranger in two sets separated at their inner or adjacent ends by an annular space at the longitudianl center of the drum. The two sets of paddle blades are so inclined with respect to each other that the backward thrust of the blades upon the water will tend to push the water toward the longitudinal center line of the boat. In other words, as seen in Fig. 3, the blades which are at any time at the bottom of the wheel are inclined, from the outer ends of the drum, inwardly and forwardly, or toward the bow of the boat.

The annular space between the two sets of paddle blades permits the escape of any air which may be ocketed or confined by the drum and add e blades as the latter moves downward y into the Water at the forward part of the wheel.

The spiral arrangement of the two sets of blades secures a better purchase or hold of the blades on the water, because counteracting the tendency of the water to escape laterally outward from the outer ends of the blades, or actin to confine it at the center of the wheel, there y iving increased efficiency in the paddle wheel and avoiding vibrations thatare liable to occur when the blades are parallel with the axis of the wheel. Moreover, the action of the two sets of spirally arranged blades in throwin the water to the center rather than sprea in it sidewise avoids the tendency which usua ly exists, of displacing the water in such manner as to lower the stern of the boat. The employment of the closed drum to support the paddle blades has the advantage of preventing the water from rising or dashing up into the center of the wheel and serves to confine the water being acted upon in a manner to afford a greater resistance to the backward movement of the blades. Moreover, the contral annular space between the blades provides an outlet for the air which, in the case of a closed drum, is liable to be pocketed by the blades between the drum and the water, as hereinbefore stated.

Instead of the spirally arranged propeller blades b b shown inFigs. 1 and 3 of the drawings, said blades may be longitudinally curved with their concave sides arranged to act upon the water; such concave sides facing toward the stern of the boat when the blades are in the water. A construction of this kind is illustrated in Fig. 11 wherein a paddle wheel drum M is shown, having two sets of oblique, curved blades m m.

Most of the advantages gained by the arrangement of the paddle wheel blades ohliquely and in two sets will be obtained when the closed drum is absent, although a addle wheel provided with a closed drum is referred for reasons hereinbefore stated. "ow referring to the construction illus trated in the engine or motor C and the connection of its crank shaft C with the paddle wheel B, said crank shaft C is parallel with the shaft B of the paddle wheel, and driving connections between said crank shaft and paddle wheel shaft are provided, which are located at the ends of said shafts and 2djacent to the sides of the boat. The end walls of the housing A for the paddle wheel are located closely adjacent to the side walls of the hull, a space being left between same sufficient only to afford room for such driving connections. By this construction I am enabled to make the paddle wheel of maximum length or nearly as wide as the boat.

The driving connections illustrated in the drawings consist of cranks C U (shown as having the form of crank-disks) provided with crank pins 0 and like cranks B on the ends of the paddle whee shaft (also shown as having the form of crank disks) pro vided with crank pins 6 and connecting rods C engaged at their ends with said crank pins 0 and b the two pairs of crank pins at opposite ends of the two shafts being arranged at an angle of 90 degrees apart, in order to avoid dead centers.

The connecting-rod drive described has the ad antage of being a simple and positive drive. occupying little Lateral space and therefore enabling the ends of the paddle wheel housing to be located close to the sides of the hull of the boat and as a consequence permitting the use of a propeller wheel nearly equal in length to the width of the hull. Moreover, by the employment of such a. connecting-rod drive, motors of standard constructionmay be employed, it being manifest that if the crank shaft of the motor were connected direct to the paddle wheel shaft, the length of the paddle wheel would have to be lessened or specially constructed motors employed. The com 'neeting-rod drive described is especially applicable to high power motors adapted to propel the boat atvariable speeds. hile the said connecting-rod drive described has especial advantages,'as hereinbefore pointed out, so far as othe. features of my invention are concerned any other form of engine or motor and connection between the same and the paddle wheel shaft may be used. and any other form of driving connections may be employed between the ends of a motor crank shaft arranged as illustrated and the paddle wheel shaft.

It. i intended that the paddle blades shall always be immersed in the water at a certain predetermined depth. For this purpose the paddle wheel is so mounted on the boat as to bevertically movable or adjustable according to variations in the submerged depth of the hull. To provide for such vertical adjustment of the paddle wheel, the end walls or heads of the housing A are provided with vertically extending curved slots A, as indicated in Fig. 9, through which 'wheel may freely rise.

slots pass the ends of the paddle wheel shaft B; said slots having the form of circular arcs concentric with the crank shaft of the motor, and said paddle wheel shaft is connected with the motor frame by means of distance or radius rods B mounted concentrieally with the engine shaft and provided with bearings 12 b for said paddle wheel shaft. By the employment of said radius rods the distance between the engine crank-shaft and the paddle wheel shaft B is maintained constant, notwithstanding the vertical ad 'ustment of the paddle wheel.

The paddle wheel shaft-bearings 7) mayeither be adjustably supported and left free to rise. or may be adjustably held at a desired elevation. As illustrated in 1 to 9, the said shaft bearings are udjustably supported in such manner that the paddle For this purpose, vertical surmorting rods K K are attached to the said bearings Z) 7) and extend upwardly through horizontal plates K K (Fig. 9) attached to the top wall of the housing A; said supporting rods being provided with screw threaded upper ends to which are applied adjusting nuts 1: 1-, 'forming stops for contact with said plates. In

order that the paddle wheel may be free to rise above the point at which it is supported by the rods K K, the said rods are adapted to slide upwardly through the said plates K K. This construction enables the paddle wheel to lift or rise in case it comes into conand lowering the pad 10 wheel, as will be usually necessar in the case of large boats, in order to avoi contact of the paddle wheel with the bottom in shallow places. mechanism of this kind is shown in Fig. 10, in

which like rods K K have at their upper ends rack teeth 1" engaging pinions K K on an operating shaft K extending across the top of the wheel housing. Such an operating shaft may be actuated either manually or through the medium of driving connections between the same and the motor C, or other engine.

Now referring to the construction and arrangement of the hydroplane members with respect to each other and to the propelling or peddle wheel, these parts. as shown in the drawing, are made as follows: The three hydroplans members D, E and F, at the forward end of the hull, are arranged in fixed angular relation'to the bottom surface of the had, and are inclined backwardly and downwardly toward the stern of the boat. Said members D, E- and F will preferably have the same width as the part of the hull on wnieh they are located; or, in other words, will be progressively 'ider from the bow toward the stern and will conform at their side edges with the contour of the sides of the hull. Said hydroplane members are shown as consisting of metal plates rigidly attached at their forward margins to the flat bottom of the hull and connected with the hull at their rear ends or margins by transverse supports or supporting walls (I and e, as indicated by dotted lines. The rear V-shaped marginal parts of said hydroplane members D and E extend rearwardly from the vertical shoulders at e in the form of lips or flanges D E, as clearly seen in Figs. 2 and 3. The said forward hydroplane members D. E and F are, moreover, made progressively deeper from front to rear; the rear end of the rearmost member F being lower thar the rear ends of the others and being loaded near the level of the bottom or lower part of the paddle wheel B.

In Fig. 3'the dotted lines F indicate lateral extensions on the hydroplane member F. This is a construction that me. be used ander certain conditions, as where a narrow hull is desirable and the projection of the hydroplane members outwardly ,from the side of the hull would not be objectionable. The preferred construction, however, is that shown in full lines in Fig. 3, wherein the sides of the hydroplane members coincide with the sides of the hull. This construction has the advantage that the hydroplane members do not project beyond the sides of the boat and are not therefore liable to be injured by striking against docks or other 1 boats.

Itis intended that the forward hydroplane member D shall have a long slope or curve of such angle as to keep the bow at proper I depth. This construction, in connection with the pointed form of the bow, is such t that when the forward part, of the hull strikes waves or swells. the crest of the wave will be divided and partly thrown to each side of the bow and will then be leveled down and surmounted as the wider part of the bow reaches it. It will, of course, be understood that the second and third forward hydroplane members E producing this etiect, especially in connection with the construction by which the tapering bow is extended fully half the length of the boat. and also by making the said members 1), E and l" successively Wider and deeper in draft, as hereinbefore stated.

The hydroplane members G and Ii, at the rear of the propelling or paddle wheel, differ from the forward hydroplane members; the

same being made of flexible metal plates,

which are secured at their forward margins i to the Hat bottom of the hull and are vertically adjustable at their rear ends, and the metal plates constituting said hydroplane members being bent or curved downwardly to a greater or less extent when their rear ends are so vertically adjusted.

Referring to the construction of the hydroplane member G, which is located immediately at the rear of the addle wheel B, the forward end thereof is ocated at a. considerable distance above the level of the rear edge of the forward hydroplane member F; the same, as shown, being located above the level of the bottom line of the hull. The rear margin of said hydroplane member G is made of Vshape, the same having two oblique edges 9 g, which meet at; an obtuse point or angle at the center line of the hull, said angle or point being directed rearwardly. The rear portion of said hydrolane member G is, moreover, made V-shape in transverse section, or has its central longitudinal center higher than its side margins, as clearly shown in the sectional view, Fig. 8. Said oblique rear margins y y of the hydroplane member G are located substantially in a horizontal plane, so that the surface of the water passing rearwardly therefrom will be in a horizontal plane, notwithstanding the arched or V-shaped cross sectional form of the rear art of the member G. Because of the angu ar relation of the rear edges g g), the angle of which to each other is such that while the said edges are in a horizontal plane, a center line drawn longitudinally through the hydroplane member will intersect the point or apex at the intersection of the edges 9 g while the side margins of said and F aid in i member will meet. the outer ends of said margins g g, as clearly' shown in l-ig. 7, which illmti'ates the said member in ide clevation. The purpose of arching the said bydroplanc member G at its rear end, in the manner eescribed, is to produce a deflection I ofthe water beneath the member toward the center thereof, rather than to force it latorally outward or sidewisc, thereby giving :enhanccd lifting etlcct, and avoiding the tendency, which exists in hydroplane boats I having successive hydroplane members, to

drop or run low at the stern. ably holding the rear end of said hydroplanc nn-mber (i at the desired height or elevation, I p1 ovide adjustable supporting means connected with the rear marginal part of said member at ditl'erent points alon the same; this construction serving to hold the center and side portions of tne member in proper relative vertical positions, notwithstanding l the flexible character of the sheet metal of [which it is made. I have shown in the drawings as a means for so adjustabl supporting the rear end of said member (5:, a. rock-shaft L, mounted in the hull of the boat, and extending transversely thereof. Said rock-shaft is provided with three eccentrics, one l located at; its longitudinal center and the two others Z Z near its ends. Said eccentrics are engaged by the upper ends of connecting rods L L L the middle rod L being connected at its lowe. end with the hydroplane member G at the center of its rear margin. while the rods L If are pivotally connected therewith near its side edges. The rear margin of said hydroplane member G is shown as having secured to its top surface, a transverse, marginal, stifi'ening bar or plate G, to the upper surface of which is secured lugs g 5 to which the lower ends of said rods l) L If are respectively pivoted. For turning the rock-shaft idly attached crank arm I, having connected with its ontercnd a longitudinally extending operating rod L As clearly seen in Fig. 5. the hull of the boat is provided with upright tubes (2 a a located respectively at. the center and at the sides thereof, in position for the passage therethrough of the said connecting rods L L L.

The eccentrics Z Z Z being set at the same angle on the rock shaft L, it; tollows that ii the same be turned, the middle and side portions of the rear end of the hydroplane member G will be raised and lowered to an equal extent. and its margins g 1 thereby retained 5 in substantially the same horizontal plane, 3 in all vertical positions to which the rear end 5 of said member may be adjusted. In effecting the vertical adjustment of the rear end of said lrvdroplane member G, the same will be bent or flexed at its forward part, where l it is substantiallyfiat or not arched.

For adjust- I The rear end of tho rearmost hydroplane member It may be adjusted by devices of the same character as above described in connection with the member G. The adjust-ing devices for said member H are not illustrated except that there is shown in Fig. 2 the lower end of a connecting rod it,

which one of a plurality of connecting rods corresponding with those employed to supportthe member G. The rear end of said member l'l may be like the rear member G, that is to say, it may be V-shaped or arched in cross section, but, as shown, it is fiat at its rear end and provided with a straight, horizontal rear margin.

The hydroplane member G is shown in the drawings as made longer from front to rear than the members D. E and F at the forward part of the hull. The forward end of said liydroplane member G is located above the level of the rear end of the forward member F, and above the level of the bottom of the paddle wheel B, in order to permit the water to pass rearwardly from the paddle blades without interference, or

'to leave a clear passage for such water.

The construction described in the transversely V -shaped or arched hydroplane -membcr' G has advantages by reason of be- .iO ing adapted to deflect the water beneath it toward the center line of the boat. and hydroplane members of lik construction may be employed in place of one or more of the members I); E, F and H, illustrated. or may be used upon hydroplane boats which in other respects differ from that illustrated,

5 and when so used may be located in any desired position on the hull of the boat.

'11 propelling device embracing a paddle 40 wheel arranged as described constitutes a ropelling means part-iculally adapted to ydroplane craft and having several important advantages over a screw propeller when applied to such craft, particularly in the case of boats of small power. T hescrew' propellen while advantageous for the ordinar speeds of displacementboats, quickly arrives at its. maximum effect for higher speeds and to greatly increase the number of revolutions of such screw propeller involves a rapidly increasing percentage of loss of power in forcing the arms and the ineti'ectiveparts of the blades through the water. In my propelling device, as compared with a screw propeller, when the peripheral parts or b a wheel enter the water they act upon the watcr at a slight depth only, but embrace a ath of considerable width or one nearly as wide as the hull of the boat. The blades are 0 therefore adapted to act by direct rearward pres ilre with a relatively large surface of contact, thereby avoiding the wasting of ower in'downward thrust upon the water and by contact of the water with parts of \(lLS of the paddle the blades so near the center of rotation thereof as to have relatively little vpropcllin etl'cct. Moreover, by vertical adjustment 0 the paddle wheel, the blades may be maintained in position to act most effectively upon the water and the same is adapted for use in shallow water where weeds and grass would interfere with the operation of a screw propeller.

The. arrangement described of the prooeller or paddle wheel with respect to the iydroplane member or members at the rear thereof is of great advantage, because the momentum imparted to the water as it leaves the blades of the paddle wheel is utilized to provide a greater elliciency of said rear hydroplane member or members; the rearwardly moving water impelled by the blades acting on said rear hydroplane members to increase the lifting ett'ect t acreof. Moreover, the location of a. hydroplane member directly in advance or forward of the propeller wheel is of great advantage because such hydroplane member tends to produce a forward movement of the surface water beneath the paddle wheel, with the result of increased efiectiveness of the paddle wheel, because the forwardly moving water better resists the rearward thrust of the, paddle wheel blades. In other words, as the hydroplane member or members in front of the paddle wheel pass over the water, they impart to the surface water a forward movement or produce a forwardly moving currentand the blades of the paddle wheel acting backwardly on this forwardly moving or opposing current, act with increased power, or with the same power at a less speed of movement, as compared with the efiect produced in a hydroplane boat driven by a. submerged screw propeller; it being manifest that m the latter case the blades of the screw propeller are too deep in the water to act upon and gather force from the forwardly moving surface current so produced by the action of a hydroplane member forward of it.

The general advantage gained by the construction in which a hydroplane member or members is located at the rear of a transversely extending paddle wheel, will be understood from consideration of the fact thatby the action of the paddle wheel blades a certain quantity of the surface water is given backward movement in relation to the 1 surrounding body of water and, since a hydroplane gains its sustaining power by reason of the relative motion or speed of the boat and the water, an advantage in lifting power is gained by the coaction of the said 1 hydroplane members (arranged at the rear of the paddle wheel) and such backwurdly moving current of water.

The employment, in a hydroplanc boat having substantially a fiat bottom, of hydroplane members constructed of flexible material attached at their front ends or margins to the bottom of the hull and adjustable at their rear ends, is of great advantage because enabling the angle at which said members act upon the water to be varied, as well as the depth of the rear ends of the hydroplane members with relation to each other.

Another important feature of my invention is the construction of the hydroplane boat with a pointed bow, like that of an ordinary boat, but with a flat bottom and hydroplane members extending across the bottom. This construction is of advantage for the reason that the pointed how has the effect of neutralizing the effect of the waves and the swells from other boats, making a much greater speed possible, while securing effective action of the hydroplane members in lifting the hull above the water.

So far as the arrangement of the paddle wheel with re pect to the hull and the forward hydroplane member immediately in advance of it is concerned, the construction illustrated is of great advantage because by reason of the forward wall of the casing or housing A and the rear end of the hydroplane member F extending downwardly in front of the paddle wheel, the water is prevented from striking the propeller blades at too high a point or in a manner to retard their downward movement, with consequent loss in propelling power. Moreover, the construction last referred to is such that the blades of the paddle wheel act or. approximately a uniform amount of water. regardless of the depth to which the boat hull and paddle wheel are submerged, because, as above stated, the hydroplane member forward of the paddle wheel deflects or depresses the water in front'of the paddle wheel and prevents the same from resisting the movement of the downwardly moving blades.

The paddle wheel arranged in such manner that a part of the hull of the boat extends downwardly in front thereof, thereby afi'ording uniform relation of the paddle wheel blades to the water beneath it, as hereinbefore stated, acts with substantially e ual advantage at high speed asa hydrop ane propeller and at low speed as a propeller for a displacement boat.

The paddle wheel will be preferably driven at a high rate of speed, and have small diameter, combined with its shallow depth of blades. This results in the water leaving the wheel quickly without the waste of power which would result in a lifting of the water by the rising blades. Ordinarily,

it is intended that the paddle wheel be adjusted to brin the blades thereof at a depth below the bottom of the boat found most efficient in practice and no adjustment afterward to provide for changes from high to low speed, or the reverse, will be necessary.
